I have 2 RH 6.1+updates boxes. I have all the updates. There is a
PPP phone line and some regional network between them. I pop up an
emacs on the one from the other, and a local netscape beside it. I
have enlightenmnet set to follow pointer focus. The remote emacs has
a slight delay responding to my keystrokes because of the packet
roundtrip time. If I move the mouse out of emacs and into netscape
and emacs is still processing X events, focus can jump back to the
emacs up to one whole second after the mouse moves from emacs to
netscape, even though the pointer is still in netscape. I don't have
to do much to make this happen. For example, if I get a cookie that
overlaps the emacs window and I go to click "cancel", the cookie
window goes away and exposes emacs. Without typing, I immediately
move my mouse out of the emacs and back to netscape. Focus goes to
netscape and I start doing things, and then focus jumps back to emacs.
It is 100% reproducible.
A similar thing happens within a single application, saoimage (there's
an rpm at rpmfind.net) that has several sub-windows in its single
application window. Start it with a private colormap, move the mouse
around, and pretty soon the colormap will get out of sync with the
mouse location, and you'll get the application colormap all the time
*except* when the mouse is in the main image window.
